AB  - In this work, two types of solid paraffins (i.e., linear and branched) were added 
      to high-density polyethylene (HDPE) to investigate their effects on the dynamic 
      viscoelasticity and tensile properties of HDPE. The linear and branched paraffins 
      exhibited high and low crystallizability, respectively. The spherulitic structure 
      and crystalline lattice of HDPE are almost independent of the addition of these 
      solid paraffins. The linear paraffin in the HDPE blends exhibited a melting point 
      at 70  degrees C in addition to the melting point of HDPE, whereas the branched paraffins 
      showed no melting point in the HDPE blend. Furthermore, the dynamic mechanical 
      spectra of the HDPE/paraffin blends exhibited a novel relaxation between -50  degrees C 
      and 0  degrees C, which was absent in HDPE. Adding linear paraffin toughened the 
      stress-strain behavior of HDPE by forming crystallized domains in the HDPE 
      matrix. In contrast, branched paraffins with lower crystallizability compared to 
      linear paraffin softened the stress-strain behavior of HDPE by incorporating them 
      into its amorphous layer. The mechanical properties of polyethylene-based 
      polymeric materials were found to be controlled by selectively adding solid 
      paraffins with different structural architectures and crystallinities.
